Hello!
I wonder, is there any way to show K2 plugins tabs in frontend edit form (Image,SIG, Attachments,AllVideo Extra Fields, and so on) ? look at screenshots in attachments

Just Check parameters.. then be sure you added your name (user) to user group.

im in Site Owner group, show K2 in tabs option. Front-end item editing.
But there are no additional tabs in frontend edit

Solved by reinstalling
